Embodiment Construction

[0033] In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0034] The embodiments of the present invention aim at the problem that the identification of different virtual machines in the same computer by means of hardware indicator lights in the prior art cannot effectively prevent virtual machines from being counterfeited, and there are problems of high hardware cost and fixed form of expression, and provide a computer.

[0035] Such as figure 2 As shown, the computer includes: a hardware platform; a virtual machine manager installed on the hardware platform; and at least one guest operating system installed on the virtual machine manager; one or more guest operating systems include an identification information management module, It is used to generate an identifier and embed the identifie...

Abstract

The invention provides a device and a method for identifying a client operation system in the computer which belong to the computer field for solving that the prior art uses hardware method can not identify real client operation system. The device includes: a client operation system which includes a manage module with sign information for generating uniform sign and embedding all signs into the client operation system attributed by the manage module with sign. The method can identify the real operating client operation system efficiently, has advantages of saving cost, multiple represent form and satisfying user's requirement.

Description

technical field [0001] The invention relates to the computer field, in particular to a device and method for identifying a guest operating system in a virtual technology-based computer. Background technique [0002] In current computer applications, the use of virtual machines has become increasingly popular. In the virtualization architecture of existing computers, multiple guest operating systems (Guest OS) are usually run on the virtual machine manager (VMM), such as figure 1 shown. For example, in a safe financial management project, a first client operating system with a high security level is used for financial management operations, and another client operating system is used for daily web browsing and other operations. If the client operating system used for daily web browsing is maliciously implanted with a Trojan horse program by others to create a virtual interface of a safe financial client operating system without the user noticing it, it may lead to the succ...
